kernel 2.4.18 with Tekram Dc-390U3W ( Symbios Logic 53C10-10 )

[vincent]

Hi,

My server is running with Slackware 8.0 and kernel 2.4.18. I got a
Pentium with a U160 SCSI Controller  ( Tekram DC-390U3W ) / 3COM 3C905C and
128 MB
RAM.

Compilation ran ok but I got some general performance problems. I have
one client connected to this machine through samba system. At the
beginning I directly looked at my network system and I changed a lot
of TCP/IP parameters but my client cannot write more than 200 - 220
ko/s ( client 10Mps on this server 100Mbps ). My client can well
download at ± 950 ko/s. This is all running fine but write sequence
takes a while and I think that I normally could have upload with
650-700 ko/s.

So I am now looking at my SCSI interface. Maybe problem comes from
there or eventually my Reiserfs config.

I compiled the kernel without applying patch-2.4.18.gz.

So my questions are the following :
- do I have to apply this patch ???
- I took driver "SYM53C8XX Version 2 SCSI support". Is that the right
one ( is that stable enough ??? ) or do I have to take another one ???
- do you see something wrong in the result of my dmesg command that
can degrade write process ...

Thanks
vincent
